[kepler-dev] Kepler source + eclipse

Hello David,

Strange thing is, that this directory is created only when I execute
"ant run" - it is not created when I execute "ant compile".

Anyway, even when directory exists, Kepler still fails to locate it when
I start it from Eclipse:

michalo at rhodiola:~/kepler.modules$ pwd
/home/michalo/kepler.modules
michalo at rhodiola:~/kepler.modules$ ls kepler-1.0-jar-tag/
configs             kar                 libexpat.dll      resources
copyright.txt       kepler-1.0.jar      licenses.txt      src
createDemosLink.sh  Kepler.app          loaddmg.sh        target
demos               kepler-console.bat  log4j.properties  tests
hsql-license.txt    kepler.exe          META-INF          website
hsqlTool.bat        kepler-kernel.iml   null              workflows
installer           kepler.sh           plugins
INSTALL.txt         lib                 README.txt
michalo at rhodiola:~/kepler.modules$

as you can see, "kar" directory can be found in kepler-1.0-jar-tag

michalo at rhodiola:~/kepler.modules/kepler-1.0-jar-tag/kar$ pwd
/home/michalo/kepler.modules/kepler-1.0-jar-tag/kar
michalo at rhodiola:~/kepler.modules/kepler-1.0-jar-tag/kar$ ls
actors  directors
michalo at rhodiola:~/kepler.modules/kepler-1.0-jar-tag/kar$ find . -name "*"
.
./actors
./actors/ArrayMinimum.kar
./actors/SshFileCopier.kar
./actors/Expression.kar
./actors/EndGAMESSInput.kar
...


BUT

if  I create a symbolic link:

shell>ln -s /home/michalo/kepler.modules/kepler-1.0-jar-tag/ null

Kepler is able to start correctly!

It looks like Kepler reads "_libraryDir" from somewhere - and this value
is empty.

I have gone once again all the steps according to

https://dev.kepler-project.org/developers/teams/build/documentation/build-system-instructions

Issue remains :(

Before starting from the scratch, I have also tried these. Situation was
the same.

I don't use any additional modules, yet. I base only on svn code so far.
I have following directories:

michalo at rhodiola:~/kepler.modules$ pwd
/home/michalo/kepler.modules
michalo at rhodiola:~/kepler.modules$ ls
build-area  kepler-1.0  kepler-1.0-jar-tag  loader
michalo at rhodiola:~/kepler.modules$

It looks like everything is just fine. Anyway, in Eclipse I don't get
any errors related to source code. Everything seems to be fine. The only
issue occurs during startup.

If you have any further suggestions, I can check them.

Cheers
